mesos git commit: HTTP Scheduler should EXIT when MasterDetector creation fails.

HTTP Scheduler should EXIT when MasterDetector creation fails.

The master detector is created during construction of the
`MesosProcess`.  If the flags cannot be loaded or if the
`MasterDetector::create` fails, the master detector will be null and
will result in a segfault if it is used during initialization.
